Description

  The present invention relates to a front end jig of an electric hammer that presses a base part of a flange part or cleat part of a conveyor belt and a base belt, and more particularly, a base part and a base belt of a flange part or a cleat part of a steeply inclined conveyor belt. It is related with the front-end | tip jig | tool of the electric hammer which can crimp | crimp.

  Conventionally, as a configuration of a steeply inclined conveyor belt, an ear beam called a flange portion formed in a bellows shape is provided at both side edges in the longitudinal direction of a base belt having a predetermined width, and a longitudinal belt is provided between the flange portions. Horizontal bars called cleat portions are provided at predetermined intervals in the direction (see, for example, Patent Document 1 and Patent Document 2).

  By the way, the flange part and the cleat part as described above are not directly fixed on the base belt, but are vulcanized and bonded in advance to a base member of a plate-like rubber member called a base part. It is interposed and laminated on the base belt and bonded and fixed.

  When the base member and the base belt are pressure-bonded and fixed with an adhesive interposed therebetween, the air between the base member and the base belt is generally used by using an electric hammer in order to discharge the entrainment air when the members are pressed. The method of extracting is performed.

  In such a crimping operation, as shown in FIGS. 26 and 27, a crimping location, for example, the top portion 1a of the flange portion 1 or the top portion of the cleat portion (not shown), the inside or outside of the flange base portion 2 or the cleat base portion, etc. Depending on the location of crimping, the air evacuation operation is carried out while properly using tools such as the electric hammer 3, the pliers, the pressure roller, and the wood hammer 4.

For this reason, there are problems that a plurality of crimping tools are always required, a lot of labor and time are required, and work efficiency is poor. Moreover, since the top part 1a of the flange part 1 and the top part of a cleat part have a small contact area, hitting a top part directly with the front-end | tip of the small diameter main axis | shaft 3a of the electric hammer 3 was a dangerous and skill-intensive work.
